The 2006 Yamaha YZF-R1 LE livery, which was a yellow, black, and white homage to Kenny Roberts Sr., is perhaps the greatest livery ever to adorn an R1, straight from the Yamaha factory. Whether you are a loyal subject of King Kenny, or you just enjoy the fetching, yet simple, racing design, the Roberts livery is a treasure to see in any form — but especially so at speed. Giving us a glimpse as to what the 2015 Yamaha YZF-R1 would look like with such a limited edition paint scheme, Oberdan Bezzi has once again whet our appetite ahead of a weekend full of riding. And for you Giacomo Agostini fans, there is something special waiting for you after the jump as well. Enjoy!

After first showing us the Honda SFA and Honda CRF250 Rally concepts, Big Red made good on its promise for another motorcycle concept premiere at the Osaka Motorcycle Show, debuting the Honda Bulldog concept. With the face of a Ruckus, and built to “leisurely” take-on the great outdoors in an unassuming manor, the Honda Bulldog is a stout off-roader that adds a new slant to the term adventure-bike. With wide 15″ knobby tires, a 28″ seat height, and 400cc parallel-twin engine mated to a six-speed gearbox, the Bulldog certainly isn’t what you expect to see bombing down the trails, yet it sorta makes sense.

If you believe the reports coming out of India and Southeast Asia, Yamaha is working on a naked version of its YZF-R25 sport bike. Presumably to be call the Yamaha MT-25, the naked bike would continue Yamaha’s trend of making naked version of its fully faired sport bikes, similar to the recently released Yamaha MT-125 that is available for the European market. With images of the machine testing on public roads abounding, the MT-25 seems likely to see production, so the real intrigue will be in what markets Yamaha makes the machine available. With Honda already offering faired (Honda CBR300R) and unfaired versions (Honda CB300F) of its small-displacement motorcycle in the US, Yamaha could easily go head-to-head with Big Red with the YZF-R3 and an FZ-03 variant, based off the R3 design.

Need further proof that the future of motorcycling will include electrics? Take this recently published patent application from Kawasaki, that the Japanese OEM filed for back in 2011. The claims are fairly rudimentary, though they do include a transmission, with Kawasaki’s lawyers mostly outlining the basics of a motorcycle powered by an electric motor, of course the news is less about the contents of the patent application, and more about the fact that it was applied for, in the first place. When will we see an electric motorcycle concept from Kawasaki is anyone’s guess, though there are two big motorcycle shows coming up in Japan in a couple weeks’ time. In reality, we doubt we’ll see something so soon from Kawasaki, but if the Kawasaki H2 has shown us anything, it is that anything is possible from Kawasaki right now.

Why would KTM be riding around on a camouflaged Aprilia Tuono V4? That is the question of the day, after a spy photographer caught the Austrian company testing in Spain with such a machine. The answer of course points to KTM working on a V4 street bike platform, which shouldn’t be too surprising since KTM CEO Stefan Pierer already tipped the media off to the fact that it is working on a MotoGP entry that would be based around a beastly V4 engine called the RC16. While Pierer confirmed the MotoGP, as well as a track-only consumer version of the GP bike, zie Austrians have been mum about other motorcycles in KTM’s lineup sharing the new V4 powerplant.

Adventure riders, you prayers have been answered. Honda is set to debut a new off-road model at the Osaka Motorcycle Show, the Honda CRF250 Rally. Based off the Honda CRF250L platform, the Rally concept is basically the CRF250L with rally-styled bodywork. The Honda CRF250 Rally concept will get its worldwide debut alongside the Honda True Adventure concept, which we first saw at last year’s EICMA show. This makes for an interesting dichotomy, as the CRF250 Rally is set to look like the CRF450 Rally race bike, while the True Adventure (cough, Africa Twin, cough) borrows heavily from the race bike’s technology package. With Honda showing a 250cc ADV model and a 1,000cc model at the same show, one has to wonder when a consumer-level version of the CRF450 Rally race bike will be ready as well.

After it first debuted in Indonesia last October, the Honda SFA concept motorcycle seems to be getting serious, as Honda will be showing the up-market bike at this weekend’s Osaka Motorcycle Show and next weekend’s Tokyo Motorcycle Show. While Honda only mentions that the SFA concept is a “street-fighter style light-weight motorcycle with a single cylinder engine mounted on a trellis frame,” sources in Indonesia say the fetching small-displacement machine is built around the 150cc CB150R for that market. Whether this means that Honda will make more premium-focused 150cc machines, and bring them to markets outside of Asia remains to be seen, though it is clear that the Japanese firm is taking such an approach under serious consideration.

Italy’s favorite boutique brand will be back at the Isle of Man TT races this year, with a two rider team that includes American Brandon Cretu. Cretu and his teammate Ben Wylie will campaign for Bimota at the big four road races (North West 200, Isle of Man TT, Ulster Grand Prix, and Macau GP) on-board the Bimota BB3 superbike. This is not the first time that Cretu and Wylie have raced together, having shared a pit while at the Wylie Racing team during the 2011 and 2012 Isle of Man TT races. Though the Bimota BB3 was ruled ineligible for FIM events, the international road racing scene has no hang-ups letting the S1000RR-powered superbikes lineup on the starting grid.

We are still waiting for the 2015 MV Agusta F4 RC to break cover officially, but the top-of-the-line superbike from Varese continues to make itself sneakily available to the public. First there were the leaked studio photos, which looked spot-on to the photos MV Agusta USA teased us with at its press launch earlier this year. Now, we have more photos of the F4 RC leaking, though with some changes to the design — namely more prominent “AMG” badging, for MV Agusta’s newest minority partner. The 2015 MV Agusta F4 RC isn’t supposed to arrive at dealerships until June 2015; and when it does, it will be in limited numbers. The F4 RC is MV Agusta’s homologation special for World Superbike and domestic superbike racing classes.

Aprilia Racing boss Romano Albesiano has big shoes to fill. Taking over from Gigi Dall’Igna, Albesiano must continue the legacy of success which his predecessor left for him. He got off to a good start, Sylvain Guintoli lifting the World Superbike title in Albesiano’s first year at the helm. Now comes the hard part, following up on that success and expanding into MotoGP. A small group of journalists spoke to Albesiano at the Aprilia launch in Milan. In a wide-ranging conversation, the Aprilia boss covered many topics, including explaining why the Noale firm came back to MotoGP a year ahead of schedule, touching on what the new bike Aprilia is working on for 2016 and beyond might look like, and the 2016 rules in MotoGP.

After losing the first day of practice at Motegi to the weather, Race Direction has announced contingency plans for a schedule to allow practice, qualifying and the races to be run at the Japanese circuit however the weather turns out.

With rain set to continue on Saturday morning, but clear up on Saturday afternoon and Sunday, schedules have been drawn up to take account of all the possible combinations of weather.

The problem is not the rain, it is the fog and low-hanging clouds, Race Director Mike Webb explained in a press conference at Motegi. Because of the location of the Twin Ring circuit, set in a bowl up in the hills in the Tochigi district in Japan, the combination of heavy clould and relatively weak winds saw the surrounding hills cloaked in cloud.

That cloud, and the reduced visibility it caused, meant that the medical helicopter, which is required to transport injured riders to the nearest hospital, was not allowed to fly, Japanese aviation law preventing helicopters flying in such circumstances. The helicopter had not yet arrived at the circuit, being stationed a few minutes flight time away.

Without the medical helicopter, practice could not be run safely, as the hospital designated by the chief doctor at the circuit is an hour away by road. Should a rider sustain a severe or life-threatening injury, they could not be transported to the hospital quickly enough to ensure proper care, Webb explained.

The lack of visibility was why Friday practice had been postponed all day, rather than canceled right away. Practice could not go ahead without the helicopter on site, but it was waiting on standby for permission from the Japanese aviation authority, ready to fly to the circuit as soon as they were given clearance. The cloud never lifted enough for the helicopter to be allowed to fly, however, and in the end, practice had to be called off.

All Friday practice sessions for the Japanese Grand Prix in Motegi have been cancelled due to safety concerns caused by adverse weather conditions. Heavy fog along with constant rain and low cloud cover have hovered over the circuit since the early morning and have failed to clear throughout the afternoon.

After the farcical yet compelling Australian Grand Prix, the Grand Prix paddock heads north to Japan for the last of the three overseas races. The contrast could not be greater: from unusually warm weather at the magnificent, sweeping Phillip Island circuit, it is cold and very wet conditions which greet the riders at Motegi, a circuit dominated by stop-and-go corners with little rhythm to it.

While almost every rider on the grid adores Phillip Island, you would be hard pressed to find a rider not holding a Japanese passport with any affection for Motegi. The challenges the riders face are mainly of physical endurance, with very few spots testing their mettle and skill.

Adding the test of endurance will be the weather this weekend. Though Typhoon Francisco has now weakened to a tropical storm and is forecast to pass much further south than was feared, large amounts of rain are still expected at Motegi, especially on Friday evening and Saturday morning.

While all of practice looks set to be wet, at least the riders will get some practice, as early forecasts had suggested that several, if not all, sessions could be a complete washout. For now, it just looks like the riders will be cold and rather wet. That could add to some real excitement at the Japanese circuit. The championship is still far from decided in all three classes, after the surprises at Phillip Island stirred up the title fight.

After the eventful Australian Grand Prix at Phillip Island, the MotoGP paddock heads to Japan, hoping for a slightly quieter weekend. It looks like they may well get their wish, thanks to the weather predicted for the Japanese Grand Prix at Motegi.

Typhoon Francisco, an intense tropical depression, is set to hit the Islands of Japan this weekend, blowing through on Friday night and departing by Saturday afternoon. With Francisco forecast to dump large quantities of rain in the region around Motegi, free practice could well be a washout, with the rain only letting up on Saturday afternoon.

We have already brought you the report of Casey Stoner testing the 2014 Honda RC213V and HRC’s “production racer” machine, the Honda RCV1000R. And, we have already brought you a bevy of photos from that test. Well now, we are bringing you another little video action from Stoner’s recent GP test at the Twin Ring Motegi circuit — just for good measure.

Here at Asphalt & Rubber, we miss Casey Stoner racing in the MotoGP Championship. That may not be the most popular opinion, especially with MotoGP fans, as the Australian never really warmed up to being in the spotlight, dealing with the prying questions of the press and demands of fans. Casey called things the way he saw it, and always strived for more on the track — and this ruffled many, as they viewed his words as complaints instead of his pursuit of perfection.

As critical of himself as he was of the machinery, tracks, and other riders, Stoner raced on a different level. There is an understanding of motorcycle racing dynamics in the two-time World Champion’s mind that few GP racers can match, and the proof of that is in Stoner’s results. It is this understanding the HRC hopes to tap into whenever they have they Aussie test a machine for them.

Taking to the Twin Ring Circuit in Motegi, for yet another test with Honda, Stoner rode back-to-back an early iteration of the 2014 Honda RC213V as well as the 2014 Honda RCV1000R “production racer” that non-MSMA teams will race next season. We have 26 high-resolution photos of Casey on these bikes after the jump, for your viewing pleasure.

While the 2013 MotoGP season has been favored with fair weather, Casey Stoner’s testing duties for Honda have been severely hindered by rain.

The previous test was a washout, and most of the last two days at Motegi were also badly affected by rain. However, the Australian managed to cram the better part of two days’ work into a single day on Thursday, riding both the 2014 RC213V and Honda’s production racer, the Honda RCV1000R.

Getting on the track one out of the two planned days at the Twin Ring Motegi Circuit last week (Day One was hampered by rain), Suzuki Racing got some more time on the track with its MotoGP race bike. With test rider Randy de Puniet on the track, the Frenchman posted a 1’48:60 as his best lap time of the day, about the same pace as his previous outings in Japan, though on par with the less grippy post-rain conditions.

Able to push the Suzuki to a GP race pace, De Puniet’s input has helped steer the Japanese manufacturer. As a result, Suzuki Racing has chosen to further develop one of the two chassis configurations it brought to Motegi, and will test that chassis again next month in Misano, as the company ramps up its efforts for a 2015 re-entry into the premier class.

MotoGP fans will be pleased to hear that Suzuki Racing has been getting pressure from Dorna to enter as many wild card races as possible in 2014, which will help bolster the grid at a select number of events. If you haven’t already seen the interview videos with Davide Brivio and Randy de Puniet, we suggest you check those out. Otherwise, there are 47 high-resolution photos waiting for you after the jump. Enjoy.

One of the great joys of private testing in the MotoGP class is the lack of media control and censorship placed upon the teams. We know that this seems like a backwards concept, but since Dorna can’t block teams from filming at the track, the private tests the MotoGP squads undertake are ever-becoming media and marketing opportunities, and our latest example comes from Motegi and the Suzuki Racing MotoGP effort.

With a season and a half to go in that endeavor, fans are now getting the treat of watching Suzuki develop in real time. Queue the team videos from Motegi, where Davide Brivio talks about the results of the test, and hired gun Randy de Puniet explains the progress with Suzuki’s new chassis. 2015 can’t come soon enough.

Completing two days of testing for HRC, Casey Stoner was back in the saddle of a MotoGP machine this week (at Motegi, of all places). The former World Champion only did a handful of laps on Tuesday (six in total) before the rain came in to the Twin Ring Motegi Circuit; but on Wednesday, Mother Nature cooperated a bit. Getting to do 47 laps in total on the 2013 Honda RC213V race bike yesterday, Stoner tested some “small items” for his former employer.

Positive about the test and being back on a bike, Stoner reaffirmed his decision to stay out of MotoGP, and dashed the hopes of any fans that were hoping to see the Australian make a wild card run at Phillip Island. Much to the disappointment of the media, Stoner did not get a chance to swing a leg over Honda’s planned MotoGP Production Racer, though HRC Executive Vice President Shuhei Nakamoto confirmed that a future test of the machine by Stoner is in the works.

A private test, and thus free of Dorna’s video restrictions, the fine folk at HRC have put together a short video of Casey on-board the RC213V in Japan. A far cry from the great material we got from Honda’s private test at the Circuit of the Americas in Austin (at some points in the video, we wonder if the videographer had some angry scarab beetles in their trousers), GP fans will surely still have an auralgasm as the RC213V goes by in anger.
